Grande Seconde Moon Black Enamel

Jaquet Droz’s flagship Grande Seconde collection contains the most poetic of complications, the moon phase, as a tribute to the role of astral phenomena in the origins of watchmaking. The clean aesthetic of the Grande Seconde collection, with its figure-8 dial configuration, is rendered here in black Grand Feu enamel. The lower subsidiary dial is dominated by a realistic moon, engraved out of 22K gold and mounted on a black onyx disk that rotates. It is an astronomical moonphase, which means it requires correction only once every 122 years, and is driven by an in-house automatic calibre with a silicon balance spring. A red-tipped hand indicates the date on an 18K gold ring surrounding the moon phase, while another hand indicates seconds. The moon phase can be set using the corrector at 8 o’clock. The 43 mm case is 18k red gold.
